Description of the bug:

With a platform_mappings file like:

platforms:
  @build_bazel_apple_support//platforms:macos_x86_64
    --cpu=darwin_x86_64

and this in your MODULE.bazel:

bazel_dep(
    name = "apple_support",
    repo_name = "build_bazel_apple_support",
    version = "1.3.2",
)

bazel errors with:

no such package '@build_bazel_apple_support//platforms': The repository '@build_bazel_apple_support' could not be resolved: Repository '@build_bazel_apple_support' is not defined

changing to:

platforms:
  @apple_support~1.3.2//platforms:macos_x86_64
    --cpu=darwin_x86_64

seems to work, but I believe that would require updating version each time you updated the rules

What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.
